Improving supportive care for women with breast cancer in Australia: The challenge of modifying health systems

Although the benefits of many psychosocial support strategies in improving well being in women with breast cancer have been demonstrated, few women receive these programs as part of routine care. This paper provides some recommendations, based on experience in Australia, about how access to evidence-based supportive care strategies might be improved through modification of health systems. It demonstrates the paucity of research about the costs and health service implications of psychosocial support strategies, which is vital to health planning and service delivery change. It outlines the systematic approach taken in Australia to improving psychosocial support nationally by: the development of research reviews; preparation of guidelines about supportive care, implementation of programs to foster the adoption of guidelines through modification of policy, health service delivery and clinician training; and monitoring programs. Coalitions of government, health care professionals and consumers are key to effective lobbying for change. If all women with breast cancer are to receive better supportive care, there is a need for approaches which: refocus the research effort in psycho-oncology; develop more strategic approaches to generating change in health systems and health policy and foster partnerships to advocate for improved resources.

Effect of inspiratory flow on methacholine challenge in children

Regulation of inspiratory flow alters the outcomes of the methacholine (MHC) challenge in adults and cough receptor sensitivity in children. The effect of inspiratory flow on the reproducibility of the MHC challenge in children is unknown. The aim of this study was to evaluate the effect of inspiratory flow alteration on the repeatabilty of the MHC challenge in children with and without asthma. Twenty-five children undertook the MHC challenge on three different days by using a dosimeter connected to a setup that allowed regulation of inspiratory flow and pattern. Children were randomized to commence the challenges at 20 or 60 L/min, and the last challenge was performed at 20 L/min. The within-subject standard deviation, 95% range for change, and doubling dose for the differing inspiratory flow (20 vs. 60 L/min) was more than twice that of when inspiratory flow was maintained at 20 L/min for both occasions. The range of the limits of agreement of the Bland and Altman plot was smaller when inspiratory flow was constant. For short-term comparative individual studies in children, inspiratory flow should be regulated. Laboratories and research measuring change in airway hyperrepsonsiveness to MHC should determine and report reproducibility indices of the challenge so airway hyperresponsiveness changes can be interpreted meaningfully.
